Solution Overview
Problem
Data card type terminals are unable to automatically identify whether they are exchanging data with a PC or wireless CPE/AP equipment, preventing them from adjusting their working mode to a normal state.
Innovation Solution
A method and system that allows the data card type terminal to judge whether a working mode request is received from a wireless AP/CPE or PC, setting the mode accordingly, and interacting with the respective equipment to report port combinations and execute configuration management commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the data card type terminal supports multiple working modes (PC mode and wireless AP/CPE mode), then the adaptability of the terminal is improved, but the device complexity increases
Solution Approach 1:
The data card type terminal automatically identifies the connection type (PC or wireless AP/CPE) and switches to the appropriate working mode without user intervention. The terminal sends identification requests and processes responses autonomously, eliminating the need for manual mode selection and reducing operational complexity despite supporting multiple modes.
Solution Approach 2:
The terminal performs preliminary actions by sending identification requests to the connected device immediately upon connection establishment. Based on the received response (or lack thereof), the terminal pre-determines the appropriate working mode before actual data exchange begins, ensuring proper mode configuration from the start of communication.
2Ease of operation
If the data card type terminal automatically identifies the connection type and adjusts working mode, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The terminal autonomously performs identification and mode switching without requiring user input. The system automatically sends identification requests, processes responses, and transitions between working modes based on the identified connection type, making the complex identification mechanism transparent to the user and improving ease of operation.
Solution Approach 2:
The terminal uses feedback from the connected device (presence or absence of response to identification requests) to determine the connection type. This feedback mechanism enables automatic mode adjustment - if a response is received, the terminal identifies it as a wireless AP/CPE connection; if no response is received, it identifies it as a PC connection, thereby simplifying operation despite the underlying complexity.
3Productivity
If the data card type terminal implements automatic working mode determination, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The terminal performs preliminary identification and mode determination actions immediately upon connection establishment. By sending identification requests and processing responses before actual data communication begins, the system ensures the correct working mode is configured in advance, preventing delays during data exchange and improving overall productivity despite the added control complexity.
Solution Approach 2:
The automatic mode determination system operates autonomously without requiring user intervention or manual configuration. The terminal self-manages the identification process, mode selection, and working state adjustment, thereby accelerating connection establishment and improving productivity while the complexity is contained within the automated control system.

AI summary
Provided are a method, device and system for determining a working mode of a data card type terminal. In the method, when a data card type terminal is connected to a wireless AP/CPE or PC, the data card type terminal determines whether a working mode request from the wireless AP/CPE is received; if so, sets a working mode of the data card type terminal to a wireless AP/CPE working mode; otherwise, sets the working mode of the data card type terminal to a PC working mode. In the solution, when the data card type terminal is connected to the wireless AP/CPE or PC, the data card type terminal determines whether a working mode request from the wireless AP/CPE exists, if so, sets a working mode of the data card type terminal to an AP/CPE working mode, while if not, sets the working mode of the data card type terminal to a PC working mode, so that the data card type terminal can automatically adjust, through interaction with the PC or wireless AP/CPE device, the working mode according to different working environments without manual interference of a user.
